4.5 Interaction with other medicinal products and other forms of interaction

4.6 Pregnancy and lactation
As with all medication caution should be exercised especially during the first trimester of pregnancy. Cumulative experience with Sodium Cromoglicate suggests that it has no adverse effects on foetal development, it should be used in pregnancy only where there is a clear need.
It is not known whether Sodium Cromoglicate is excreted in human breast milk but on the basis of its physico-chemical properties, this is considered unlikely. There is no information to suggest the use of Sodium Cromoglicate has any undesirable effects on the baby.
4.7 Effects on ability to drive and use machines
As with all eye drops, instillation of Opticrom may cause a transient blurring of vision or local irritation that could impact driving or operating machinery. Do not drive or operate machinery if affected.
4.8 Undesirable effects
Transient stinging and burning may occur after instillation. Other symptoms of local irritation have been reported rarely.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.
4.9 Overdose
No other action other than medical observation should be necessary.
5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Ophthalmologicals; Other antiallergics, ATC Code: S01GX01
In vitro and in vivo animal studies have shown that Sodium cromoglicate inhibits the degranulation of sensitised mast cells which occurs after exposure to specific antigens. Sodium cromoglicate acts by inhibiting the release of histamine and various membrane derived mediators from the mast cell.
Sodium cromoglicate has demonstrated the activity in vitro to inhibit the degranulation of non-sensitised rat mast cells by phospholipase A and subsequent release of chemical mediators. Sodium cromoglicate did not inhibit the enzymatic activity of released phospholipase A on its specific substrate.
Sodium cromoglicate has no intrinsic vasoconstrictor or antihistamine activity.
5.2 Pharmacokinetic properties
Sodium Cromoglicate is poorly absorbed. When multiple doses of Sodium Cromoglicate ophthalmic solution are instilled into normal rabbit eyes, less than 0.07% of the administered dose of Sodium Cromoglicate is absorbed into the systemic circulation (presumably by way of the eye, nasal passages, buccal cavity and gastrointestinal tract).
Trace amounts (less than 0.01%) of the sodium cromoglicate does penetrate into the aqueous humor and clearance from this chamber is virtually complete within 24 hours after treatment is stopped.
In normal volunteers, analysis of drug excretion indicates that approximately 0.03% of Sodium Cromoglicate is absorbed following administration to the eye.
5.3 Preclinical safety data
None stated
